A coupled model for healthy and cancerous cells dynamics in Acute Myeloid Leukemia
(IFAC, 2014)In this paper we propose a coupled model for healthy and cancerous cell dynamics in Acute Myeloid Leukemia. The PDE-based model is transformed to a nonlinear distributed delay system. For an equilibrium point of interest, ... -
Dwell-time computation for stability of switched systems with time delays
(IET, 2013)The aim of this study is to find an improved dwell time that guarantees the stability of switched systems with heterogeneous constant time-delays. Piecewise Lyapunov-Krasovkii functionals are used for each candidate system ... -
A new model of cell dynamics in Acute Myeloid Leukemia involving distributed delays
(2012)In this paper we propose a refined model for the dynamical cell behavior in Acute Myeloid Leukemia (AML) compared to (Özbay et al, 2012) and (Adimy et al, 2008).We separate the cell growth phase into a sequence of several ... -
A numerical method for stability windows and unstable root-locus calculation for linear fractional time-delay systems
(Elsevier, 2012-08-14)This paper aims to provide a numerical algorithm able to locate all unstable poles, and therefore the characterization of the stability as a function of the delay, for a class of linear fractional-order neutral systems ... -
On the analysis of a dynamical model representing gene regulatory networks under negative feedback
(Wiley, 2014-07-25)In this work, stability analysis is performed for a cyclic dynamical model of gene regulatory networks involving time delays, under negative feedback. The model considered has nonlinearities with negative Schwarzian ... -

Stability analysis of a dynamical model representing gene regulatory networks
(2012)In this paper we perform stability analysis of a class of cyclic biological processes involving time delayed feedback. More precisely, we analyze the genetic regulatory network having nonlinearities with negative Schwarzian ...
